Abstract: Systems and methods for adjusting an operating parameter of a machine based on an operating state of a component of the machine are provided. A method may be implemented by an electronic control unit (ECU) of the machine and includes determining that a performance of the machine has degraded. The method further includes selecting a predetermined adjustment to the operating parameter, wherein the selected predetermined adjustment reduces an effect of the operating state of the component on the performance of the machine, and operating the machine using the selected predetermined adjustment to the operating parameter.

Abstract: A hybrid-electric propulsion system for an aircraft includes a turbomachine, the turbomachine including a first spool and a second spool. A method for operating the hybrid electric propulsion system includes operating, by one or more computing devices, the turbomachine such that the first spool mechanically drives a prime propulsor of the hybrid-electric propulsion system; and modifying, by the one or more computing devices, a speed relationship parameter defined between the first spool and second spool by providing electrical power to, or drawing electrical power from, an electric machine mechanically coupled to the first spool, the second spool, or both.

Abstract: A method for operating a gas turbine engine having a starter-electric generator driven by one of a plurality of shafts of the gas turbine engine is provided. The method includes determining a desired amount of thrust to be produced by the gas turbine engine, as well as a desired amount of electrical power to be drawn from the starter-electric generator of the gas turbine engine. The method operates the gas turbine engine to produce the desired amount of thrust, while drawing less than the desired amount of electrical power from the starter-electric generator. Drawing less than the desired amount of electrical power from the starter-electric generator allows for the desired amount of thrust production, allows for the desired amount of thrust production more quickly, or allows for maintenance of a stall margin for any purpose (such as to increase an efficiency of the engine or to allow for certain engine designs).

Abstract: A control system may generate a first simulated value for an aircraft sensor by applying one or more first input parameters to a sensor map model via a processor. The control system may compare the first simulated value and the first output of the aircraft sensor to determine a first calibration value and save calibration data in a memory based on the first calibration value. The control system may generate a calibrated simulation value of the aircraft sensor based on the sensor map model and the calibration data. The control system may determine validity of a second output of the aircraft sensor, utilize the second output of the aircraft sensor to perform an operation of the aircraft when the second output of the aircraft sensor is valid, and utilize the calibrated simulation value to perform the operation of the aircraft when the second output of the aircraft sensor is invalid.
